In major Indian cities like Delhi, Mumbai, Chennai, Bengaluru, Kolkata, and Hyderabad, rising temperatures have resulted in worsening heat stress due to increased concretization and urban sprawl contributing to the Urban Heat Island Effect. The Centre for Science and Environment highlights the impact of climate change, land use changes, and rapid urbanization on heat stress, particularly affecting vulnerable groups.
Heat stress occurs when the body cannot effectively release excess heat, leading to physiological strain and health issues. Factors exacerbating heat stress in urban areas include air and land surface temperatures, humidity, and the Urban Heat Island Effect. Measures are needed to address these challenges and protect vulnerable populations such as the elderly, pregnant women, and outdoor workers.
The World Health Organization warns that heat stress caused by climate change could lead to 38,000 additional deaths annually worldwide between 2030 and 2050. It is crucial to understand the Urban Heat Island Effect, which describes higher temperatures in urban areas compared to rural surroundings due to human activities and urban characteristics.
To combat heat stress, efforts have been made to implement measures to mitigate the impacts of heat waves. While some progress has been achieved, more comprehensive strategies are needed to ensure the protection of vulnerable populations and enhance preparedness for future heat waves.
Understanding the causes and effects of heat stress is essential in developing sustainable urban planning and infrastructure to combat rising temperatures in major cities like Delhi, Mumbai, and Bengaluru. By addressing the challenges posed by heat stress, India can work towards creating a healthier and more resilient environment for its citizens.
